Knee Pain

Based on your answers (you are older than 45, no other joints are bothering you, your painful knee is swollen and there is no locking and/or giving way of the knee), there are a number of possible causes of knee pain. More than one may be present at the same time, including:

osteoarthritis

crystal-induced disease such as gout and pseudogout

infection (less likely)

ligament or cartilage damage (though one of these would be even more likely if you had locking or giving-way)
